The Cubs placed pitcher Brad Wieck on the 10-day injured list Friday with an irregular heartbeat. He had heart surgery in February 2020 to repair an atrial flutter, and he started experiencing the irregular heartbeat earlier this week.
Wieck has been wearing a heart monitor for the last several days, and it reported the irregular heartbeat while he was sleeping. The Cubs trusted he was healthy enough to pitch earlier this week, but have shifted to a position of greater caution.
“With his history, I mean anything you’re dealing with is extremely serious,” manager David Ross said.
